As Timothy mentioned, Solr has the PostFIlter mechanism, but it's not really suited for ranking/sorting changes. To effect the ranking you'd need to work with the TopScoreDocCollector which Solr does not give you access to. If you're doing distributed search you'd need to account for the ranking algorithm at the aggregation step as well.
There is a pluggable collectors jira that builds under Solr 4.1 (SOLR-4465) but it is a proof of concept at this time. You may want to chime in on this ticket if you find it useful.
